WhatsApp

WhatsApp is a cross-platform messaging application developed by Meta Platforms, Inc., originally founded in 2009 by Brian Acton and Jan Koum. It allows users to send text messages, voice messages, make voice and video calls, share images, documents, user locations, and other media. The service operates over the internet, requiring a mobile phone number for registration, and is available on smartphones and desktop computers. Acquired by Facebook (now Meta) in 2014 for approximately $19 billion, WhatsApp has grown into one of the world's most popular communication tools, with over two billion monthly active users as of recent estimates. It emphasizes end-to-end encryption for all messages, ensuring privacy and security. The platform supports group chats, broadcast lists, and status updates, integrating with other Meta services like Instagram and Facebook. WhatsApp's simplicity, reliability, and free cost have made it a staple in personal and business communication globally, particularly in regions like India, Brazil, and Europe. It faces competition from services like Telegram and Signal but maintains a strong market position due to its widespread adoption and network effects.
